OCI Generative AI

Oracle Cloud Infrastructure (OCI) Generative AI is a fully managed service that provides a set of state-of-the-art, customizable large language models (LLMs) that cover a wide range of use cases, and which are available through a single API. Using the OCI Generative AI service you can access ready-to-use pretrained models, or create and host your own fine-tuned custom models based on your own data on dedicated AI clusters.
To use, you should have the latest oci python SDK and the langchain_community package installed. 
pip install -U oci langchain-community
See chat, complete, and embedding usage examples.
